Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic plating facility for supplying a machined work from its stock yard to an automatic plating apparatus and collecting it again in the stock yard after plating.

[0002]

2. Description of the Related Art Equipment for plating a large number of works in large quantities has already been automated up to the supply of works to a plating apparatus and the collection after the processing. In such an automated plating processing facility, in order to promote the efficiency of processing, a method is adopted in which a work is stored in a hooking jig and the hooking jig is fed as a unit to a line. In order to improve the processing efficiency including the interlocking with the automatic plating device and the loading and unloading of pre-processed and processed workpieces, the one with a stockyard connected to the line to the automatic plating device has been conventionally used. The equipment is common.

From the stockyard to the automatic plating equipment,
A line such as a conveyor for transporting the hooking jig is provided,
The hooking jig containing the unprocessed workpieces stands by in the stockyard and is sequentially transferred to the automatic plating device.

In such a double equipment of the stockyard and the automatic plating apparatus, it is necessary to transfer the hooking jig from the stockyard to the automatic plating apparatus or vice versa. This work is performed manually or in a large facility mainly by a dedicated robot.

[0005]

The hooking jig has a work stored therein, and if it is capable of processing a large amount of work at a time, its weight is considerably large. For this reason, manual work is a heavy burden, and the size of the hooking jig is also limited, so there is a limit to improvement in processing efficiency.

On the other hand, when a robot is used, high precision is required for positioning when the hooking jig is transferred between the stockyard and the automatic plating apparatus, and therefore it is difficult to control. If this control is not sufficient, delivery of the hooking jig will be defective, and troubles and line stops will frequently occur. Further, in the case where there are various types of hooking jigs and the shape of the hook portion is large or small, the control becomes complicated, and there is a large obstacle in terms of equipment cost.

As described above, in the double equipment of the stockyard and the automatic plating apparatus, the processing efficiency depends on whether or not the hook jig is delivered between the stockyard and the automatic plating apparatus. Has a great influence on.

[0008] The problem to be solved in the present invention is to improve the interlocking property of the delivery of the hooking jig between the stockyard side and the automatic plating device side to further promote the efficiency of processing.

[0009]

According to the present invention, an automatic plating apparatus equipped with a hanger that circulates while a hooking jig is immersed in and pulled up in a tank for cleaning or plating, and the hooking jig is stocked. A facility provided with a stockyard for delivering the hooking jig to and from the automatic plating device, wherein the hanger jig is a means for delivering the hooking jig between the stockyard and the automatic plating device. It is constituted by a link between the ascending / descending operation of and the operation of the transfer means of the hooking jig provided in the stockyard.

[0010]

In the hanger of the automatic plating apparatus, the hooking jig is immersed in a cleaning tank or a plating tank and then lifted to move around each tank in order, and ascends and descends and moves around the line. On the other hand, the transfer means of the stock yard performs an operation of sending the hooking jig storing the unprocessed work to the loading portion of the automatic plating apparatus and an operation of receiving the hooking jig from the unloading portion after the processing. Therefore, if the respective operations of the hanger and the transfer means are linked, there is an interlocking relationship in which the loading means transfers the hooking jig from the transfer means to the hanger and the unloading portion receives the hooking jig from the hanger in the transfer means. Can be made.

As described above, by combining the movement of the hanger of the automatic plating apparatus and the movement of the transfer means of the stockyard, it is possible to construct a line that does not require any additional equipment at the delivery portion of the hooking jig.
